Cardiac PET imaging of blood flow, metabolism and function in normal and infarcted rats

R. Lecomte; E. Croteau; M. -E. Gauthier; M. Archambault; A. Aliaga; J. Rousseau; J. Cadorette; F. Benard; M. Bentourkia 2002 IEEE Nuclear Science Symposium Conference Record, 2002

The rat heart is an excellent model for the investigation of cardiac physiology and metabolism. It has been used extensively for ex vivo studies of the normal heart as well as for the study of various heart diseases. With the advent of dedicated high-resolution small animal PET scanners, it is now possible to transpose many of the cardiac investigations routinely ...


Investigation on deadtime characteristics for simultaneous emission-transmission data acquisition in PET

Yuan-Chuan Tai; A. Chatziioannou; M. Dahlbom; E. J. Hoffman 1997 IEEE Nuclear Science Symposium Conference Record, 1997

Modern PET systems utilize rotating rod sources and sinogram windowing for transmission scan and are capable of simultaneous emission-transmission data acquisition. Count rate capability of a PET system using EGO is mainly limited by deadtime of block detectors. Deadtime of a EGO block detector is directly associated with the rate of single events. In a simultaneous acquisition, moving rod sources ...


MicroPET II: an ultra-high resolution small animal PET system

Y. -C. Tai; A. F. Chatziioannou; R. W. Silverman; K. Meadors; S. Siegel; D. F. Newport; Y. Yang; J. Stickel; S. R. Cherry 2002 IEEE Nuclear Science Symposium Conference Record, 2002

MicroPET II is a second-generation microPET scanner dedicated to high resolution PET imaging of small animals. The system consists of 90 scintillation detector modules arranged in a 3-ring configuration with a radius of 16.0 cm and ail axial extent of 4.9 cm. Each detector module consists of a 14×14 array of lutetium oxyorthosilicate crystals coupled to a multi-channel photomultiplier tube ...


On accelerated cross-reference maximum likelihood estimates for positron emission tomography

H. Horng-Shing Lu; Wen-Jie Tseng 1997 IEEE Nuclear Science Symposium Conference Record, 1997

The state of art of positron emission tomography (PET) takes into account the accidental coincidence events and attenuation. The maximum likelihood estimator can handle this kind of random variation in the reconstruction of a PET image. However, the reconstruction is ill-posed and needs regularization. The boundary information, either from an expert or from the other medical modality of the same ...


Sampling considerations for high resolution small animal SPECT

C. Damiani; G. Di Domenico; E. Moretti; N. Sabba; G. Zavattini; A. Del Guerra 2002 IEEE Nuclear Science Symposium Conference Record, 2002

Using the small animal hybrid PET/SPECT scanner YAP-(S)PET we demonstrate how oversampling is important to improve both image quality and spatial resolution in SPECT modality. Due to the planar configuration of our pixellated detector we can easily perform oversampling by shifting detector heads from the central position of an amount smaller than the detector pixel size. Oversampling, together with the ...
